Ecological wood is not wood-plastic material
Ecological wood is a new type of environmentally friendly materials, he entered the Chinese market has been seven years, and it has many names: ecological wood, wood, plastic wood, the Great Wall of wood, ecological board, etc., and here and There is no single standard.
Since 2006, the national wood-plastic industry standards committee on the “eco-wood” industry-standard formulation of the work, and with the end of 2012 is completed, is expected to be early 2013 to the public.
Wood as the national standard-setting industry participants, eco-wood industry standards by the Chinese Wood Industry Association named “wood-plastic composite profiles.” The national level of the name as has been shown that “eco-wood” is a wood-plastic composite material is a kind of profile. Then wood and ecological wood what is the relationship between it.
Ecological wood is not wood-plastic material? Wood plastic material definition
WPC refers to the use of polyethylene, polypropylene and polyvinyl chloride, instead of the usual resin adhesive (containing formaldehyde and other harmful substances), and more than 35% -70% of wood flour, rice husk, straw and other waste plant fiber mixed Into a new wood materials, and then by extrusion, molding, injection molding and other plastic processing technology to produce the plate or profile.
The ecological wood is the use of pvc (that is, vinyl chloride in the polymerization initiator with the thermoplastic resin) and wood flour, enhancer, calcium powder, foam and other thermoplastic thermoplastic extrusion material. Therefore, ecological wood is a kind of wood.
One of the earliest wood-plastic materials is classified as eco-wood, due to the difference between foaming and non-foaming, another material is now known as the pe-type eco-wood material. So eco-wood is divided into: pe ecological wood and pvc ecological wood, and are wood-plastic.
Eco-wood is not wood-plastic material? Ecological wood called composite profiles is why?
So, why is the ecological wood called composite section it, because the wood itself is a composite material is very easy to explain. More important now ecological wood materials can be used as decoration materials, such as ecological wood keel, ecological wood shade louver box. In addition, eco-wood decoration does not require painting, do not need to do other processing, that is equipped with, is a good profile.
Due to habitual problems, ecological wood will not change according to the national name of the formulation, but we must remember that eco-wood is divided into two types is a pvc type pe type, but are wood-plastic materials.
